Legendary NFL coach Marty Schottenheimer has been dealing with early-onset Alzheimer's disease for the past five years, ESPN reported Friday.

Tony Grossi of ESPN reported that Schottenheimer is in good health and still plays golf every week, but is beginning to suffer memory loss.

"He's in the best of health, [but] sometimes he just doesn't remember everything," said Schottenheimer's wife, Pat. "He functions extremely well, plays golf several times a week. He's got that memory lag where he'll ask you the same question three or four times."

She added: "He remembers people and faces, and he pulls out strange things that I've never heard, but he's doing well. It's going be a long road. We both know that."

Schottenheimer coached in the NFL for 21 seasons, with stints in Cleveland, Kansas City, Washington, and San Diego. He never made the Super Bowl, but boasted an impressive record of 200-126-1. He last coached in 2006, leading the Chargers to a 14-2 record. They were knocked out of the playoffs that season by the Patriots in the first round.

NFL Power Rankings: Week 8

32. Browns (0-7)
Last Week: 32

Another week, another Browns loss. The Jets, Cleveland's Week 8 opponent, is having as turbulent a season as anybody. So maybe -- just maybe -- there's hope.

31. Bears (1-6)
Last Week: 31

After a few weeks of Brian Hoyer showing promise, he's now injured and Jay Cutler will be back under center for Week 8. Woof.

30. 49ers (1-6)
Last Week: 30

As bad as the 49ers are, they still have the edge over Cleveland and Chicago.

29. Panthers (1-5)
Last Week: 27

After a Week 7 bye, Carolina has to get its season back in order quickly -- but against Arizona this week, it won't be easy.

28. Saints (2-4)
Last Week: 25

The Saints may have one of the worst defenses the franchise has ever had. They'll win games if Drew Brees can keep up with the points his defense allows, but even for an all-time great, it's a tall task.

27. Jaguars (2-4)
Last Week: 22

Seems like we can officially write off the Jaguars once again after another offseason of hype. At 2-4, they're dead last in the AFC South.

26. Titans (3-4)
Last Week: 24

Tennessee had a chance to hop back into the division race with a win over Indianapolis, but squandered their chance. Still just 3-4, the Titans are overperforming a bit, to their credit.

25. Rams (3-4)
Last Week: 21

With any sort of talent at quarterback, the Rams would be in a much better position. But Los Angeles' offense just isn't capable of doing serious damage.

24. Jets (2-5)
Last Week: 29

Good news: The Jets finally won their second game. Bad news: After one game, Geno Smith tore his ACL, and their season is back in the hands of the league-leader in interceptions, Ryan Fitzpatrick. And a salty Ryan Fitzpatrick, at that.

23. Ravens (3-4)
Last Week: 19

Baltimore's skid continued with a loss to the Jets, and their 3-0 start can now be fully be credited to the quality of their competition.

22. Dolphins (3-4)
Last Week: 28

Miami took down one of the AFC's hotter teams last week when they beat Buffalo, continuing their bewilderingly inconsistent season. If they can keep up performances like that, they may be able to sneak into the postseason conversation -- but they're just too hard to trust.

21. Colts (3-4)
Last Week: 26

Indianapolis got back on the winning side in Tennessee last week, but still has some work to do to catch up in the division. A win next week at home against a good Chiefs team would help convince fans that they're for real.

20. Buccaneers (3-3)
Last Week: 20

Tampa Bay isn't nearly as bad as San Francisco -- they handled the Niners with ease on the road. But can they handle a good Raiders team?

19. Chargers (3-4)
Last Week: 23

San Diego finally enjoyed a good win against Atlanta -- their roster simply has too much talent have dropped to 2-5. They'll face a tough opponent in Denver next week, but a win would even up their record at 4-4 and firmly place them in the middle of the pack.

18. Texans (4-3)
Last Week: 11

Boy, are the Texans lucky they're in the tire fire that is the AFC North. It took Brock Osweiler 41 pass attempts to reach 131 yards on Monday night, giving Houston little chance against Denver.

17. Lions (4-3)
Last Week: 18

The Lions gutted out a close win against Washington, pushing their record back over .500. After nearly two months of inconsistency, a victory over Houston next week could kick their season into gear.

16. Giants (4-3)
Last Week: 16

The Giants were lucky to escape London with a win thanks to a last-minute Case Keenum interception, but nonetheless head into their bye week over .500. Still, in a competitive NFC East, they're tied for last place.

15. Redskins (4-3)
Last Week: 12

Washington's hot streak ended with a loss to Detroit, and they'll travel to London next week to face a Bengals team that's struggled to string together consistent success. They'll try to jump out to 5-3 before their Week 9 bye.

14. Bengals (3-4)
Last Week: 17

Cincinnati handled the Browns, as expected, and now travel to London to try and even their record back up at 4-4 before a bye week.

13. Bills (4-3)
Last Week: 10

The Bills could've crept to within a game of the Patriots before their Week 8 matchup, but suffered a bad loss to Miami last week. Not great, but you know Rex Ryan will have his bunch fired up to play at home against the Patriots.

12. Falcons (4-3)
Last Week: 7

Atlanta remains atop the NFC South, but are dangerously close to slipping back into last year's trend of complacency after a good start. Against Green Bay next week, they'll be in danger of falling back to .500

11. Raiders (5-2)
Last Week: 14

In a game the Raiders of old would surely lose, Oakland beat Jacksonville on the road to improve their record to 5-2 at the top of the AFC West.

(Photo by Rob Foldy/Getty Images)

10. Eagles (4-2)
Last Week: 13

Philadelphia, fittingly, became the first team to deliver Sam Bradford a loss this season. A huge game awaits them next week -- on Sunday night in Dallas.

9. Steelers (4-3)
Last Week: 6

Without Ben Roethlisberger, the Steelers' offense is merely mortal. Against New England, it was bound to fail, but a bye should help Roethlisberger at least get close to full health.

8. Cardinals (3-3-1)
Last Week: 15

Despite playing to a tie, it was encouraging to see Arizona play up to the level of competition as high as Seattle. They'll be hoping that performance -- sans their kicking game -- can get them back on track.

7. Chiefs (4-2)
Last Week: 9

Despite a lack of flash, the Chiefs proved again that they're still among the league's most well-rounded teams with a Week 7 win. A number of winnable games lay ahead for Kansas City, so be on the lookout for them to shoot even higher up this list in the weeks to come.

6. Packers (4-2)
Last Week: 8

Green Bay took care of Chicago last week as expected, but still need to prove that they can consistently beat good teams. Against Atlanta, they'll have a shot.

(Photo by Stacy Revere/Getty Images)

5. Cowboys (5-1)
Last Week: 4

After a bye, Dez Bryant could be back in the mix for Dallas, which makes their offense even more scary.

(Photo by Hannah Foslien/Getty Images)

4. Vikings (5-1)
Last Week: 2

They suffered their first loss this week, but the Vikings' stingy defensive crew should be able to keep them near the top of this list as long as Sam Bradford continues to keep them close in games.

(Photo by Rich Schultz/Getty Images)

3. Broncos (5-2)
Last Week: 5

Trevor Siemian didn't give them much in Week 7, but a strong running game and a stout defense firmly places the Broncos among the league's best.

2. Seahawks (4-1-1)
Last Week: 3

After New England, the conversation for No. 2 gets murky. Despite Stephen Hauschka's struggles last week, we like Seattle's makeup moving forward.

1. Patriots (6-1)
Last Week: 1

After seven weeks, the Patriots remain the lone truly dominant team in the NFL. A win against the Bills this week could already wrap up the AFC East discussion.
